To 10720122 it may concern.

Be it known that I, Anrnuo A. GILMonE, a citizen of Canada, r siding at Preston, in the Province of Ontario and Dominion of Canada, have invented a new and useful Gothic Roof for Barns, of which the following is a specification.

This invention relates to the construction of a roof which is particularly adapted for barns, and which is a modification of the type generally termed. Gothic.

The general object of the invention is to provide a construction for the roof which will be artistic in appearance, which will provide a maximum storage space for the ground area which the barn covers, and which will be of maximum strength for the amount of material used.

It is a special object of the invention to provide a construction by which roofs of any size may be built up from units carried in stock, sothat the greater part of the cu ting may be done at the mill, thus saving expense in transportation. as well as in the framing, and making it possible to complete the building with a minimum amount of labor.

It is also an object of the invention to provide improved means for securing and bracing the roof so as to leave the interior of the barn practically free of obstructions, without in any way weakening the structure.

The detailed construction by means of which the invention is carried out will be best understood from a consideration of the following description taken inconnection with the accompanying drawings, which illustrate the invention in its preferred form.

In the drawings:

Figure 1. is an end view, half in section and half in elevation. of a barn constructed in accordance with the invention.

Figure 2 is a side elevation of the barn, showing portions of the same completed and other portions with merely the framing.

Figure 3 is a side elevation of a. pair of rafters, illustrating the method of cutting the same for barns of different widths.

Figure 4 is a View looking from the right hand side of Figure 3.

Figure 5 is a perspective view of one of the rafters.

Figure 6 is a perspective of one of the units from which the rafters are built up.

The frame of the barn includes side studs nected by tie-beams 0r joists 15, the intermediate portions of which rest on longi tudinal girders 16, which are supported by posts 17. The side and end studs are connected by a series of girths 18 and 19, respectively, which support the siding.

The rafters 20, which are arcuate, extend from the ends of the joists 15 upwardly and inwardly and meet to form a ridge 21, the upper ends of each pair of rafters being connected by a short tie-bar 22. Each rafter is made up of a series of units 23 of uniform size-and shape, and are uniformly bored at 2% to receive bolts 24: for splicing the units together in overlapping relation, with the joints between the units staggered as shown in Figure 5. In this manner a rafter of any desired length may be built up from these units. The rafters are thus made of sulficient length to form an arch, as shown in Figures 1 and 3. Each arch is. formed of two rafters with their bases coinciding with the side walls of the barn, and with their upper ends meeting at the apex 21 and joined by the tie bar 22. In Figure 3, the line B represents the total height of the roof, and the line W represents the total width. If it is desired to make the barn two feet narrower than shown, the upper ends of the rafters are cut off, as indicated at c by vertical cuts, one foot in horizontal distance from theepex 21, thus making the height of the roof as indicated by the line B. If a still narrower barn is desired, the upper ends of the rafters may be cut, as indicated at c and 0 making the height of the roof as indicated at the lines B respectively.

In order to brace the roof and secure the same rigidly to the main part of the frame, the studs 10 are extended some distance above the joists l5, and the upper ends con.- nected to the lower portions of the rafters by side ties 30 and 31. The upper ends of certain of the studs 10 and the rafters 20 are also braced from the tie-beams 15 by braces 26, which are secured to each by bolts. It will be noted, however,.thatthe side ties. 30 and 81 rigidly connect the studs to the rafters, and consequently make it possible to omit the greater portion of the braces 26,

and B thus leaving the interior of the barnunobstructed except at intervals, which may run from six to twelve feet on centers. Short lookout rafters 2'? rest on the wall plates 25 and are inclined upwardly and inwardly, and secured at their upper ends to the rafters 20. Any suitable rooting, as indicated at 28, may be laid over the rafters 20 and 27 extending down over the cornice 29, so as to form an artistic and serviceable roof.

It is to be understood that the rafters 20 are all made up of standard pieces of mate rial cutto exactly the same radius, and all exactly the same length, built together to form arches. By cutting the upper ends of these rafters, as indicated, a roof of any ner herein proposed all such labor and loss of time is eliminated.

lVhile I have shown and described the specific features of the invention and the principles embodied therein, it will be understood that various modifications may be made in the size and proportion of-the parts and their relat1on to each other, such as is required by the particular construction in which it is to be used, without departing from the spirit of the invention.

Whatis claimed is:

1. In a barn. the combination of opposed series of side studs transversely connected by joists, arcuate rafters extending upwardly and inwardly from the ends of the joists au'd -meeting at the apex of the roof, said studs being extended upwardly above the ends of the joists and their upper ends connected to each other by wall plates. ties connecting the upper portions of the studs to the rafters, and lookout rafters resting or the wall plates and conne ted to the intermediate portions of the arcuate rafters.

In a barn, the combination of opposed series of side studs. a roof made of two op- -:relation,- said rafters being supported with their lower ends intermediate the ends of the respective studs, means for holding the studs and rafters against spreading, and comparatively short lookout rafters above the ends of the studs'and joined to the intermediate portions of the arcuate rafters.

3. in a barn, the combination or" a series of side studs. joists connecting the studs at a point between the top and bottom thereof, arcuate rafters extendingupwardly and inwardly from the studs where the joists are connected thereto, said rafters meeting at the apex of the roof, and .inclined braces extenthire from the upper ends of the studs to the joists and secured to and crossing the rafters at an intermediate point of their length.

4. In a barn, the combination of a series of studs arranged at each side of the barn. joists connecting the studs intermediate their ends, arcuate rafters extendingup wardly and inwardly from the studs where the joists are connected thereto, said rafters meeting" at the apex of the roof, side ties connecting: the upper portions of the studs to the rafters. and inclined braces intermediately bolted to certain of the rafters and havinp; their ends bolted to adjacent studs and joist-s respectively.

5. In a barn the combination of a series of studs arranged at each side of the barn, joists ronnecting the studs intermediate thci' ends. arcuate rafters extending upwardly and inwardly from the studs where the joists are connected thereto, said rafters meeting at the apex of the roof. inclined braces connecting the upper ends of the studs, to the joists and secured to and crossing tharafters at an intermediate point, wall plates connecting the upper ends of the rafters. and lookout rafters re'stina on the wall plates and connected to intermediate por liens of the arcuate rafters.

(3. In a barn. the combination of opposed series of side studs arranged at each side of the barn and transversely connected by joists. arcuate rafters extending upward J and inwardly from the ends of the joists and meeting at the apex of the roof, said studs being extended upwardly above the cues of the joists and their upper ends counectcd to each other by wall plates. tics connecting; the rafters to the studs above the joists. inclined braces extending from the upper ends of the studs in the joists and secured to and crossing the arcuate rafters at an intermediate point, and lookout rafters resting! on the wall plates and connected to intermediate portions of the arcuate rafters.

In testimony that I claim the .foren'oiup as my own, I have hereto 'aliixed my signature.

ALFRED A. GILMORE.
